Live outage map for Wiltshire
The map shows incidents reported by users in real time, centred on Wiltshire. Zoom in on your street to check whether a cut is your home only or a wider network fault — when neighbours are also dark, it is a National Grid Electricity Distribution job.
Salisbury Plain chalk uplands, the Avon and Wylye valleys, and the rolling Cotswold limestone in the north. Convective summer storms over Salisbury Plain cause localised cuts at Devizes and Tilshead; freezing fog in the Wylye valley ices up overhead networks.

Why the power goes out in Wiltshire
Wiltshire spans Salisbury Plain in the south, the Cotswolds fringe at Chippenham and the Swindon railway town in the north. NGED's South West licence covers the county. Salisbury Plain chalk uplands, the Avon and Wylye valleys, and the rolling Cotswold limestone in the north.
Weather and terrain. Convective summer storms over Salisbury Plain cause localised cuts at Devizes and Tilshead; freezing fog in the Wylye valley ices up overhead networks.
How the network is run. NGED depots at Swindon, Salisbury and Trowbridge dispatch engineers. The Ministry of Defence training estate on Salisbury Plain has dedicated supply protected from civilian network faults.
A local quirk worth knowing. Stonehenge and the Salisbury Plain sites have their own dedicated visitor-centre supply — public-network outages do not affect English Heritage operations.
What to do when the power goes out at home in Wiltshire
Check whether neighbours are affected
Look at the street lights and the houses opposite. If they're on, your fault is inside your home — check the consumer unit. If they're out too, it is a National Grid Electricity Distribution network fault: call 105.
Dial 105 or 0800 6783 105
Have your full postcode ready. Ask the operator for an estimated time of restoration (ETR) and a fault reference number — both make any later compensation claim faster.
Unplug sensitive electronics
Unplug TVs, routers, computers and consoles to protect them from a surge when supply returns. Leave one light switched on so you'll know visually when the power is back.
Log start and end times
A cut over 24 hours in normal weather entitles you to £75 from National Grid Electricity Distribution under Ofgem's Guaranteed Standards. Severe weather has higher thresholds and a £2,000 cap. Keep a written log with photos — most payments arrive automatically within 10 working days.

Yes. Under Ofgem's Guaranteed Standards of Performance, domestic customers in Wiltshire receive £75 after 24 hours off in normal weather, plus £40 every additional 12 hours up to £300. Severe-weather events have higher thresholds and a £2,000 cap. Payment is normally automatic from National Grid Electricity Distribution within 10 working days — claim within 30 days if it doesn't arrive.
National Grid Electricity Distribution announces planned cuts by letter (and increasingly text or email) 2 to 8 days in advance. Most run 8am to 6pm and last 2 to 8 hours. Planned cuts do not qualify for Ofgem compensation unless your DNO failed to give adequate notice (a £40 payment applies then).
